AI Customer Support CRM with Smart Ticket Routing

Problem and target customer

Why this exists

Customer problem

Growing support teams manually read and assign every inbound request. Category, urgency, sentiment, and agent expertise are applied inconsistently, causing queue imbalance and slow escalation while customer history remains scattered.

Who pays

Small customer support teams handling a shared email queue where agents have different skills and a lead still reviews sensitive escalations.

Business model

Monthly subscription priced by support seats with an included ticket volume.

Editorial note

Smart routing should be split into two inspectable decisions. The model suggests what kind of help the message needs; published team policy decides which available person is eligible to handle it.

Overrides are not failures to hide. They reveal missing skills, poor category definitions, urgency mistakes, or workload rules that should inform the next policy version and model evaluation.

A useful beta still works when AI is unavailable. Tickets remain visible, manually classifiable, assignable, and replyable, so a provider outage degrades triage speed without stopping customer support.

Product goal

Who it serves and what it must change

Target user: A support agent triaging inbound tickets and a team lead balancing assignments and escalations.
Problem: Manual classification and assignment delay first response, while opaque automation can send sensitive issues to the wrong agent.
Measurable outcome: An inbound email becomes a ticket with visible suggestions; an agent can accept or override routing, reply from the ticket, and recover safely if classification or email delivery fails.

Primary flow

Inbound email is authenticated, deduplicated, sanitized, and attached to a customer and new or existing ticket.
A worker suggests category, urgency, sentiment, and required skill with short evidence from the message.
The assignment engine ranks available agents by skill, open-ticket cap, and rotation, then stores its reasons.
An agent accepts or overrides the assignment, reads customer history, and sends a reviewed reply.
The ticket moves through Open, Waiting on customer, Escalated, Resolved, or Reopened with timestamps and ownership history.

Core entity outline

Entities and business rules

Customer

The requester identity and conversation-history boundary.

Fields: primary_email, name, company, created_at
Relations: Has many Tickets

Ticket

One support issue and its assignment and resolution lifecycle.

Fields: customer_id, subject, status, category_id, urgency, sentiment, assignee_id, first_response_at, resolved_at, reopen_count
Relations: Belongs to one Customer, Has many TicketMessages, Has many RoutingDecisions

TicketMessage

A sanitized inbound, outbound, or private support entry.

Fields: ticket_id, direction, visibility, sender, body_text, message_id, delivery_status, created_at
Relations: Belongs to one Ticket, May have Attachments

AgentSkill

An explicit category capability and proficiency used by assignment.

Fields: agent_id, category_id, proficiency, active
Relations: Links an Agent to a TicketCategory

RoutingDecision

A model suggestion, deterministic ranking, acceptance, or override record.

Fields: ticket_id, suggested_category, suggested_urgency, required_skill, candidate_agent_ids, reason, decision, decided_by
Relations: Belongs to one Ticket

Business rules

Inbound message IDs are unique per provider; duplicates append nothing and return the existing intake result.
Model output may suggest labels but cannot assign an agent or send a reply by itself.
Assignment excludes unavailable agents and anyone at the published open-ticket cap before applying skill and rotation ranking.
An override requires a reason and becomes evaluation data; it does not rewrite the original suggestion.
Resolved tickets reopen when a new customer message arrives within the retention period, preserving prior resolution timestamps.

Architecture and data flow

Components, integrations, and controls

Support workspace

Present queues, conversations, routing explanations, replies, policies, and reports.

Email gateway

Verify inbound webhooks, normalize threads, sanitize content, store attachments, and send idempotent replies.

Classification worker

Call the model with bounded ticket text, validate controlled labels, and save suggestions and evidence.

Assignment engine

Rank eligible agents using published skills, availability, caps, and rotation.

PostgreSQL and object storage

Persist customer and ticket history while keeping validated attachments private.

Integrations

Inbound and transactional email provider
LLM API for controlled classification and sentiment suggestions
Private object storage for permitted attachments
Optional Make webhook for confirmed escalation notices

Data flow

A verified email webhook is deduplicated, sanitized, and mapped to a customer and thread.
The new ticket ID queues classification; validated labels feed the separate assignment engine.
The engine stores ranked candidates and reasons, then an agent accepts or overrides the route.
Outbound text is persisted before sending, and delivery callbacks update that message without changing ticket resolution.

Failure handling

Quarantine malformed email with an intake reason and alert a lead without creating a partial ticket.
If classification fails, leave the ticket Unassigned with manual category controls and allow retry.
If no eligible agent exists, preserve the required skill and escalate to the lead queue.
A failed reply remains visible as Send failed and can be retried with the same idempotency key.

Security

Verify provider webhook signatures and block executable or oversized attachments.
Enforce agent and lead roles for routing-policy and ticket access.
Redact secrets and payment data before model calls and do not train on ticket content by default.
Keep private notes out of outbound messages, exports, and model context unless explicitly selected.

Rate limits

Limit inbound size and messages per sender while allowing trusted provider retries.
Cap concurrent classification jobs and model tokens per workspace.
Throttle outbound email by provider and customer address to prevent duplicate bursts.

Deliverables and acceptance

Definition of done for the MVP

Deliverables

Shared email support queue and ticket workspace
Controlled AI classification with evidence
Skill, load, availability, and rotation assignment engine
Reply delivery and reopen handling
Routing override and support performance report

Acceptance criteria

A valid inbound email creates exactly one customer message and one ticket or thread update despite webhook retries.
Every suggested route shows category, required skill, eligible candidates, and the deterministic ranking reason.
An agent can override a route and the original suggestion remains available for evaluation.
A classification outage leaves tickets manually actionable.
A reply provider timeout produces one visible Send failed message that can be retried without duplicate delivery.

Recommended stack

Enough technology for the first version

Web application

Next.js and Tailwind CSS

Support fast queue navigation, dense ticket history, and routing controls.

Data

PostgreSQL

Model threads, routing decisions, policies, assignments, and delivery state transactionally.

Jobs

BullMQ and Redis

Separate intake follow-up, classification, send retries, and report work.

OpenAI structured outputs

Constrain suggestions to known categories and return evidence fields the agent can inspect.

Email and attachments

Resend plus Cloudflare R2

Handle support email and keep permitted attachment bytes private.

Why this is sufficient

The model interprets ticket language, while assignment remains a testable policy over skills and workload. This separation provides an AI benefit without granting the model authority over staffing, escalation, or customer communication.
